NuFilter™ High Performance Custom RF Filters

The NuFilter™ product line includes quick-turn custom filters and complex custom filters. We design various filter topologies such as Bandpass, Highpass, Lowpass, and Notch filters.

Our QUICKFIL program provides quotations within 24 hours with a response plot and mechanical drawing. Receive your finished filter within 2 – 3 weeks after receipt of order. This program fulfills our quick-turn methodology of filters that are moderately complex in design and within the following parameters:

  • 1 to 15 GHz
  • 5% to 28% 3 dB bandwidth
  • Up to 50 W power handling
  • Bandpass Combline Cavity

Are your specifications outside of these parameters? Not to worry, we cater to a full spectrum of RF filters.

Our CUSTOMFIL program provides the same expertise, but caters to more design-intensive, complex orders. The lead times reflect this complexity and can be longer than 3 weeks, typically less than 8 weeks.

Internet From The Stars: 21st Century Space Race

Two weeks ago, SpaceX launched it’s third successful mission placing 60 more Starlink satellites into low earth orbit, bringing the total number of global internet powering satellites to 180. That is far from the planned system completion threshold of 12,000, but it does establish that SpaceX has the formula down and isn’t going to stop

Which Filter Response Type Is Best For My Application?

Why is RF filtering so important? Simply put, filters reduce the interference in the environment that affects the performance of the communication system and reduce the interference caused by the communication system. Once you have identified the system level need for a filter, it’s now time to determine which filter response type will accommodate your

The Benefits of a Tunable RF Filter

Filters are a staple of RF designers everywhere, and especially in applications where the integrity of the signal cannot be compromised. When you’re only concerned about a single frequency, it’s relatively easy to add in a fixed-tuned filter.  However, it becomes slightly more difficult when you need to cover multiple frequencies and can’t just utilize

Spectral Regrowth: Stay in Your Lane

Modern communication systems are typically based on a framework of channels, where the frequency spectrum is divided into channels of a defined bandwidth and each signal is assigned to a particular channel.  This is analogous to a highway system being divided into lanes.  On a highway, it is undesirable for a car to cross into

For Some Veterans the Battle has Followed them Home

I recently had the pleasure of assisting in the leadership of an event that was aimed at building community among the local population of military veterans in the Cincinnati region. The event was an absolute success, and it reinforced in me the positive and fun environment that can be found when a group of around

Why Gallium Nitride (GaN)?

GaN technology has been improving radio frequency (RF) systems since the early 1990’s. It’s ability to support high frequency, wide bandwidths, and high-power density make it invaluable in any market requiring high performance in a small form factor. When compared with other semiconductor technologies such as Gallium Arsenide (GaAs), Laterally Diffused Metal Oxide (LDMOS), and
